Carbon atom is tetravalent in nature. how many hydrogen atoms can bind to one carbon atom?

It is said that the carbon atom is a tetra valence which means, it contains 4 covalent bonds that can be bonded with other atoms. Therefore, it needs 4 hydrogen atoms to bind into 1 carbon atom. Carbon Atom contains a total of 6 electrons that occupies the 2 shells which is the K (have 2 electrons) and L (have 4 electrons) shells.  The outermost shell of carbon atoms that contains 4 electrons is called as valence shell. In order to complete its octet, carbon Atom needs other atoms to share their valence electrons.

Answer is to avoid experimental error

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
